HAT SWEAT-BAND.

Specification of Letters Patent.

Patented Sept, 211, an.

Application filed July 13, 1914. Serial No. 850,660.

To all whom it may concern:

Be it known that I, FRED E. HALBERT, a citizen of the United States,residing at San Diego, in the county of San Diego and State ofCalifornia, have invented a certain new and useful ImprovementinHatSweat- Bands, of which the following is a specification.

My invention relates to hat sweat-bands, and particularly to asweat-band that will minimize the pressure on the head of the wearer ordistribute it so that the blood will circulate freely throughout thescalp and thereby furnish nourishment to the hair and upper part of thehead and scalp. As usually constructed, hats and caps have been providedwith sweat-bands of leather or other material fitting closely to thehead of the wearer, thereby exerting pressure in a continuous planeabout the head which tends to compress the veins and retard thecirculation of the blood, thereby withholding from the upper part of thescalp a large portion of the nourishment which it should receive, thusworking injury to the scalp and the growth of the hair.

In United States Letters Patent No. 662,645, issued November 27, 1900, Ipartially overcame the objection above stated by providing a sweat-bandwhich would exert pressure at intervals only in the direction of itslength about the head of the wearer, and it is particularly my desire atthis time to add an improvement to the structure set forth in saidLetters Patent. Like the sweat-band described in said Letters Patent, mypresent invention consists of a sweat-band corrugated in the directionapproximately at right angles to its length on the layer or part restingagainst the sides and back of the head and reinforced with a similarlycorrugated layer of thin sheetmetal or the like to cause thecorrugations of the sweat-band, which rest against the sides and rear ofthe head, to retain their shape and not to flatten under pressure, andalso to have that portion of the sweat-band which rests against theforehead smooth and free from corrugations,-but at the same time havethe corrugated metallic reinforcing,

portion thereof continue the full length of the sweat-band.

In the drawings Figure 1 is a plan view;

- my improved sweat-band in position therein.

Similar characters of reference refer to similar parts throughout theseveral views.

A, represents a hat. I B, i is my improved sweat-band. The sweat-band Bis formed of an inner drip or layer, 6 of some soft material. such asleather or cloth, and an outer layer 6 of a hard and preferably flexiblematerial. Any sufiiciently hard material suitable for the purpose may beemployed for the layer 5 though I prefer the use of thin sheet-aluminumon account of its lightness and flexibility. This strip or layer b maybe of the same or of a less width than the layer or strip 5 The parts orlayers 5 and b may be cemented together if desired. The layer b iscorrugated or fluted throughout its entire length, and the layer b issimilarly corrugated or fluted, except the portion 5 thereof which restsagainst the forehead of the wearer, which is left plain or unfluted.This sweat-band may be attached to the hat by stitching iii the usualmanner.

When the hat isworn the sweat-band will contact with the head atintervals only along the length of the band, and at that portion of theband where the inner layer is not corrugated, the pressure will besimilarly distributed at intervals, but the plain surface of the innerlayer prevents the forehead of the wearer from being marked by a directcontact with the corrugated portions of the hat-band. By thisarrangement a comparatively small proportion of the blood vesselsrunning to the upper part of the scalp will be sub ected to pressure. Iprefer to form the head-engaging parts of the sweat-band by means of thecorrugations shown, though any other suitable form located at intervalsalong the band may be used, although care must be employed inmanufacturing the sweat-band so that the contacting parts do not extenddiagonally with relation to the hat-band.

It will be readily seen that with this construction and arrangement,when the hat is worn there is provided a sweat-band that ofiersvery'little resistance to the free circulation of the bloodto all partsof the scalp "by Letters Patent, is:

V Asweet-band, having an innerlayerof "soft inaterial and anouter leyerof rigid strengthening material, said ngid layer being'b'entto formrigid transverse head-engaging corrugations t'hrol'lghout its entire1ength, and said soft inner layer being pro vided throughout its length,except in the part thereof intended to rest against the forehead of thewearer, with transverse cor- 'rugations co-ineident with thecorrugations of said rigid strengthening layer.

In testimony whereof I have. hereunto subscribed my name in the presenceof two subscribing witnesses,

FREDE. HALBERT.
